기본정보
SCADA is "Supervisory Control And Data Acquisition,“ an automatized development tool to be applied to monitoring and controlling all automatized sites with software, developed based on Window to monitor and control social infrastructure such as power plants, railways, and ports or industrial control system which controls factories in industries.
Also, it is software to monitor and control status of each machine and measurement value / set value by installing a computer or workstation connected to automatized machines(PLC/Controller) at the site.
It is largely indicated a centered system which monitor and control specific industrial site or the whole industry complex which is geographically spread wide.
Application Field
- Machinery Equipment Automation
- Flow monitoring
- Production Control System
- Warehouse Automation
- Control Measurement System Development
Components
SCADA system is generally composed of the following components.
- Human-Machine Interface, HMI :
It is a device to show data used for machine control, conversing it to form which is familiar to human. Manager monitors and control the relevant process through this.
- Monitoring(Computer) System :
This collects data relating to process and deliver practical order to control hardware.
- Remote Terminal Unit, RTU :
This is directly connected to sensor which is installed at the process. It mutually converses signals from this to recognizable digital data, and send the data to a monitoring system.
- Programmable Logic Controller, PLC :
This is a device, in effect disposed at the site, and can be used more economically and for mulita-purposes than Remote Terminal Unit(RTU) which is designed for specific purposes
- Communication Facilities :
It makes remoted elements communicate such as control system, RTU, etc. with each other. Multi-process and Analytical device.
